Hi,

The book "Aircraft of the United States Military Air Transport Service" shows two schemes for the C-74:

1. Solid bare metal with the yellow MATS arrow and logo under the cockpit. Black band (edged in a light color) on tail with Division markings, black USAF number under that, and USAF roundel/bars under windows between wing and horiz. stab. Black MILITARY AIR TRANSPORT SERVICE over the windows (12 windows long). MATS number on nose within geometric shape.

2. Later scheme. Bare metal, with white top fuselage with black edge stripe. Black edge stripe is just above the windows. Black edging swoops up over the top of the fuselage just behind the cockpit windows, leaving a solid bare metal nose. Black U.S. AIR FORCE under the cockpit. Black edging bumps up slightly when it encounters the U.S. AIR FORCE lettering. No number on nose. All the rest the same as scheme 1, except the MILITARY AIR TRANSPORT SERVICE over the windows is much smaller (6 windows long).

Hope this helps,
